A capture compound and a method of identifying drug target non-target proteins in a mixture of proteins is provided, comprising the steps of interacting the mixture with a capture compound of the formula Q-Z-( Xm)-Yn, wherein Z is a trivalent moiety for presenting X, Y and Q; moiety X is selected to covalently bind to proteins; moiety Y is a pharmaceutical drug, drug fragment, drug metabolite, prodrug, enzyme substrate, enzyme inhibitor, transition-state analogue or a ligand to a receptor; Q is a sorting function selected to permit physical arraying or other addressable separation method suitable for analysis, Q comprises a biotin moiety, a (His)6 moiety, a BODIPY moiety (4, 4-difluoro-4-bora-3a, 4a-diaza-s-indacene), an oligonucleotide or PNA (peptide nucleic acid), an antibody, an immunotoxin conjugate, an adhesive peptide, a lectin, an activated dextran or a peptide; and analyzing the captured proteins to identify drug target or drug non-target.
本发明提供了一种捕获化合物和鉴定蛋白质混合物中药物靶标非靶标蛋白质的方法,包括以下步骤:将混合物与式Q-Z-( Xm)-Yn 的捕获化合物相互作用,其中Z是用于呈现X、Y和Q的三价分子;分子X被选择用于与蛋白质共价结合;分子Y是药物、药物片段、药物代谢物、原药、酶底物、酶抑制剂、过渡态类似物或受体配体;Q 是一种分选功能,用于物理阵列或其他适合分析的可寻址分离方法,Q 包括生物素分子、(His)6 分子、BODIPY 分子(4, 4-difluoro-4-bora-3a, 4a-diaza-s-indacene )、寡核苷酸或 PNA(肽核酸)、抗体、免疫毒素共轭物、粘附肽、凝集素、活化葡聚糖或肽;分析捕获的蛋白质,以确定药物靶标或药物非靶标。
